Campaign 4 of Critical Role is reshaping how the beloved actual-play Dungeons & Dragons series operates, introducing a structural overhaul that has fundamentally altered both storytelling and performance for its cast. As revealed in the latest episode of Tale Gate, an exclusive talk show on Critical Role’s streaming platform Beacon, co-founder Liam O’Brien openly discussed why this new format represents uncharted territory—and one that has left even veteran players navigating unknown narrative ground.
The most significant departure from prior campaigns is the adoption of the West Marches format, which splits the cast across three distinct tables: Soldiers, Seekers, and Schemers. Rather than exploring the familiar world of Exandria, the group now ventures through Aramán, a god-forsaken realm where magic behaves unpredictably and danger lurks at every turn. But beyond this unfamiliar setting lies a deeper transformation in how the cast actually plays together.
A Format That Keeps Secrets Even From Its Own Cast
The defining feature of Campaign 4’s structure is deliberate information separation. While some cross-talk may occur outside of recorded sessions, players do not necessarily know what transpires at the other tables or how those events have shaped their characters’ arcs. This design choice means that even O’Brien himself has been kept in the dark about major story developments.
“This is uncharted territory, what we’re doing in Campaign 4,” O’Brien said while addressing a question about the Convergence arc spanning episodes 26 to 31. “I used to know everything about every chapter, and now there are whole swaths of the story that I know nothing about.”

O’Brien’s revelation came when host Whitney Moore brought up a romantic hook-up between fellow players’ characters—Murray Mag’nesson (Marisha Ray) and Kattigan Vale (Robbie Daymond)—a development the actor had not been aware of. While this may seem like a minor detail, it underscores one of Campaign 4’s most challenging aspects: navigating an entire campaign without access to the full picture.
The West Marches Format in Practice
In previous campaigns, cast members occasionally missed key moments due to illness, filming commitments for other projects, or personal events. However, those instances were unplanned and sporadic. Campaign 4 takes this concept by design, adhering closely to the West Marches format in which different groups of player characters handle separate quest scenarios before reconvening to share what they have learned.
Critters witnessed firsthand how these three tables limited the cast’s knowledge during the first episode of the Convergence arc titled “Council of Heroes.” The fake resurrection of Yanessa Halovar was entirely new information for players at both the Soldiers and Seekers tables. Similarly, the true purpose behind Occtis Tachonis’s death remained unknown to neither the Soldiers nor Schemers.
The cast has acknowledged discussing Campaign 4 away from the table, but experiencing events in real time remains a fundamentally different beast. Because split tables are engineered to preserve secrecy, players can make decisions without interference from others who might harbor concerns about how those choices affect their characters or the overarching narrative.
A Solution to Past Criticisms
This structural shift also addresses one of the most prominent complaints leveled against the cast during Campaign 3. Many viewers felt the group often rested on its laurels rather than committing to decisive action. In Campaign 4, hesitation has largely dissolved as players remain too focused on immediate events to dwell on developments unfolding elsewhere.
The example of Julian Davinos (Matthew Mercer) illustrates this point well. Had Mercer been present at the same table as Azune Nayar (Luis Carazo) during their interaction with Harondus Einfasen regarding the axe Azune carried, Mercer might have inadvertently played his character differently based on knowledge he would otherwise lack.
Looking Ahead
While lacking the complete picture presents genuine challenges for the Critical Role cast, it has ultimately transformed Campaign 4 into one of the most exciting actual-play Dungeons & Dragons campaigns many fans have witnessed. The collective uncertainty—where neither players nor audience fully know what awaits next—makes every decision and its consequence feel monumental.
The West Marches format continues to unfold across ongoing episodes, with each convergence bringing new revelations that reshape relationships and storylines. As the cast navigates this uncharted territory, viewers are left wondering how these fragmented arcs will ultimately converge—and whether the secrets kept at one table will prove as devastating when finally revealed.
